MARKER HOLDER FOR PLANTERS.

Application filed June 9',

lily-invention relates to corn and cotton planters, and specifically to a mechanism for holding the marker in a fixed position on one side of the machine while travelling in one direction and on the opposite side of the machine when travelling in the opposite direction and also to holding the marker in a'secure vertical position when the planter is being transported from one place to another.

One object of my invention is to provide an attachment that can be readily adapted to machines now in use for the purpose of holding the marker securely in various positions.

Another object of my invention is to provide an attachment for corn and cotton planters that will securely hold the marker in any desired position and at the same time can be shifted from one position to another without the necessity of the operator leaving his seat.

Another object of my invention is to provide an attachment for holding the marker of cotton or corn planters in position, of such simple design that it may be readily attached by a person of average mechanical ability.

Other and further objects of my invention will be apparent from the following description and specification.

Referring to the drawings made a part of this specification Fig. l is a' plan view showing my improved attachment for holding the marker in position.

Fig. 2 is an elevation of a portion of a planter with my improved attachment in place.

Fig. 3 is a side elevation showing the marker held in position by my improved attachment.

Fig. 4 is a perspective view of my improved attachment shown disconnected from the planter.

The objection to ropes for holding markers is that the rope continually stretches, allowing the marker to move back from rectangular position, thus reducing the width of the row.

To obviate the objection above set forth, I have designed an attachment that securely holds the marker in a position at a right angle to the longitudinal axis of the machine when using the marker and that has the further advantage that the driver may with one 1924. Serial No. 718,847.

hand, without leaving his seat, shift the marker to a vertical position or tothe op posite side of the machine in-position for the return trip.

Another advantage of my invention. is that the marker is pivotally attached to the central portion'of the frame and is held securely in position by my attachment at a point intermediate of its two ends, thus affording substantial anchorage, or bracing the marker against longitudinal movement.

A still further advantage of my invention is that it may be readilv attached for use with various makes of planters now in the hands of users, and it is of such simple and sturdy construction that its use is readily understood and it requires no adjustment, because when the marker drops into position it is exactly at a right angle to the longitudinal center of the machine.

Referring to Fig. l it will be noted that the general outline of my improved attachment is substantially that of an inverted V, having its two lower ends 1l flattened and turned at approximately a right angle to the main body 2 of the V. The flattened portions 11 are provided with apertures 3 adapted to receive a bolt by means of which it is bolted to the frame at 4:, shown in Figs. 1 and 2. By reason of the fact that the attachment, as shown in Fig. 4, is made of relatively light stock, the distance between the two openings 3-3 may be in creased or decreased at will by simply contracting or expanding the V-shaped portions, thus readily adapting it to the use of various makes of planters. A U-shapcd portion 5 at the end of the V-shaped member 6 is adapted to securely hold the marker arm 7 in ahorizontal position when the marker is in use and allow room for vertical motion when the planter passes over ground of irregular contour. The marker arm 7 is pivotally joined, as shown in detail in Fig. 3, to the main frame 8 of the planter. The pivot joint 9 readily permits the rotative movement of the arm 7 from one side of the machine to the opposite side, thus it will be readily understood that the marker arm 7 is readily held in position by the U- shaped member 5 when in a horizontal position andby the U-shaped member 10, at the apex of the V, the marker arm 7 is held in a vertical position when the machine is being transported from one field to another, or elsewhere.

The distance from the pivot joint 9 to the U-shaped portions 5-5 is sufficiently great to support the marker arm 7 against movement either in a forward or' backward direction, and the distance between the pivotal connection 01 the arm at 9'and the U- shaped portion at 10 is sufiiciently great to hold the marker arm 7 in a secure position while the machine is being transported. Thus, it isapparent that my invention'fully and completely overcomes the objections above referred to and which are common to all marker holders heretofore in use.

Having thus given a full and accurate description of my improved attachment for corn and cotton planters, what I claim as new and useful and desire to secure by Letters Patent is i-- A marker holding attachment for corn and cotton, or other, planters, consisting of a substantially V-shaped member having at its apex a U-shaped portion, turned at approximately a right angle to the legsot the V-shaped portion and adapted to engage and hold in position the marker arm of a corn or cotton planter when brought into a vertical position, and having like U-shaped portions near the end of the V-shaped member, adapted to engage and hold in a horizontal position the arm of the marker when in a horizontal position, said U-shaped portions being rigidly held in position by means of bolts and nuts attaching said port1ons to the main frame of the planter.

In witness whereof I have hereunto at fixed my signature this 3rd day of June,

. WILLIAM M. KEYTH.
